HEATING-FURNACE.

SPECIFICATION forming part of L'etters Patent No. 274,676, dated March 27, 1883.

Application filed October 5,1882. (No model.)

To all whom it may concern:

Be it known that I, FELIX TYLEE, of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Heating-Furnaces, of which the following is a specification.

The nature and objects of this invention will fully appear from thesubjoined description, when considered in connection with the accompanying drawings,,in which- Figure l is a top view. Fig. 2 is a front elevation, partly in section on line 00 m of Fig. 1. Fig. 3 is a vertical section in line y yof Fig. 1. Fig.4 is an underside view of the ash-pit,showing a damper for opening a direct communication with the chimney. Fig. 5 is a detached sectional view, showing manner of securing air-tight joint at lower end of inner cylinders. Fig. 6 is a like view, showing manner of securing an air'tightjoint at topend of outer cylinder.

A is a fire-pot supplied withthe usual grate, and is supported over an ash pit or boxin the ordinary manner, and has also a feed-opening and door infront. Above said. fire-pot is arranged a set of sheet-metal cylinders, of peculiar construction, for the production of heated air and its distribution, which comprise-and embody my improvement, as follows: The top of said fire-pot is provided witha wide projecting annular flange or ring, a, which supports, the'outer cylinder, 0, in which is contained the other mechanism. This cylinder 0 is of suitable height lor the purposes for which it is intended, and is crowned with a ring, D, having a groove fitting over andresting upon the edge of said cylinder. Within said cylinder 0 is placed a tapering cylinder, E, of the same diameter at the top as the outer cylinder, 0, and the two are united at their top edges by the same ring, D. The "lower end of said cylinder E,which is about three-fourths the length of cylinder 0, is reduced by the taper to about three-fifths diameter of top, and is closed by a wide ring, F, which ring also supports a third cylinder, G,the top of which is slightly smaller in diameter than the bottom, but is of the same length as the cylinder E. The top end of said inner cylinder, Gr, is closed permanently by a cap, H, having four radial arms, 7th, the outer ends of which rest upon the top of the ring D.

smoke.

The cylinders E and G are sechred firmly together by long bolts I I, which pass through the arms h and ring F. The joint at the top of outer cylinder, 0, and cylinder E is made air-tight to prevent escape of gases by means of a welt of copper or other suitable soft metal said ring F, leaving anarrow space the width of said plate f between said two cylinders E and G. These three cylinders form three chamhers, the outer and inner chambers being combastion-chambers, and are open to the fire-pot below them, while the intermediate chamber is an air-heatin g chamber. From two opposite sides of the outer cylinder, 0, are attached cold-air pipes P P, depending nearly to the floor, and are open at the bottom for the admission of cold air. At their union with the cylinder 0 they are connected with the aforesaid air-chamber within the cylinder E bysub chambers c c, which are located at the base of.

the said chamber E and in the lower portion of the combustion-chamber and partly over the lire-pot. Consequently the air which passes through them must become quickly and thorv oughly heated. The aforesaid ring F and plate fare provided with openings 0 0 for communication between the chamberE and sub-chambers c c. On the rear side of the cylinder 0 is an opening and collar, 8, for attaching a pipe for connection with a chimney to carry off The space in the chamber C next to the hole s is divided by a partition-wall, to, up a little above the top of said hole, to divert the flames upward and over said wall for the purpose of retaining and distributing the flames before their escape to the chimney, as indicated by the arrows. The use ot the inner chamber, G,is for the consumption of the smoke and gases,which is'performed thus: The smoke and gases which pass upward into said chamber can find no escape and are returned toward the fire and nearly or quite'consumed. Behind the fire'pot is placed a pipe, T, connecting the ash-box B with the chamber inclosed by cylinder 0 behind the partition w, the lower end of which pipe is closed by a damper, t, which can be operated by a rod, '2), extending outward atthe front of the said box. The object of this pipe and damper is to supplya means for turning the draft from the firepot to the chimney direct when desired to cool down the fire.

This furnace is to be inclosed in a suitable casing of metal or brick, the heated air being conveyed by suitable pipes from the chamberE.

Having described my invention, I claim-- 1. The combination, with the-fire-pot A, having wide flange a, of the cylinder (J, tapering cylinderE, and cylinder G, the cylinders O and E being united at their top by ring D, and the cylinders E and G secured by ring F and annular plate f, and the top of cylinder G being closed by cap H,having arms h h, said cap and rings being secured firmly together by the bolts I I, the chamber inclosed by cylinder 0 having sub-chambers c c, connectingwith ch amplatef, the said sub-chambers communicatingwith the outer air through the depending pipes P P, said chamber (J also having the wall 20,

all constructed and operating as and for the purpose specified.

2. The joint consisting of the ring D, having annular groove, the welt covering the top edges of the cylinders O and E, as shown and described.

3. The joint consisting of the ring F and plate "f, uniting the lower edges of the cylinders E, in the manner and for the purpose specified.

4. The combination, with the ash-pitB and I chamber 0, of the pipe T, provided with the damper t, operated by the rod 11, as and for the purpose specified.
